BOBBIN-CLEANING MACHINE.

appara-non filed september 9, 192e. serial No. 134,434.

In textile manufacturing operations, as is well known, when roving bobbins are removed (for replacement by filled bobbins) from the creeis of fly-frames and spinning mules, small quantities of rovings usually still remainthereon; and when filling bobbins are ejected from the working shuttles of automatic looms employing feelers, small quantities of viilling, termed feeler Waste, usually remain thereon. Machines are in use for removing such remainders or residues from roving and filling bobbins, respectively. For example, a well-knowiitype of bobbin cleaner, which is employed for cleaning roving bobbins by removal of residues of rovings from the exteriors of the bobbin barrels, is shown and described in U. S. Letters Pat entNo. 1,451,239, dated April lO, 1923.

Sometimes in the case of roving bobbins portions of rovings, and more or less lint or other waste, become entered within the central bores of the bobbins, and when it is sought to effect the removal thereof opera tions'have to be performed for clearing out the said bores. These operations have been performed separately from the more or less' completely automatic cleaning or stripping of the bobbin exteriors, and have entailed additional handling of the bobbins, with an increased amount of labor and cost. The object of the present invention is to enable bobbins to be cleaned interiorly as well Vas exteriorly, in one machine, in a single passage through the machine. The invention consists, accordingly, in a machine comprising, in combination, means for cleaning the exteriors of bobbins and means whereby, also, t-lie interiors thereof are cleaned. The means for performing each division of these operations may be varied in reducing the invention to practice. For cleaning the bobbin exteriors in the case of roving bobbins the means of the Letters Patent aforesaid may advantageously be employed. For cleaning out the interior bores, pneumatic devices may advantageously be utilized, inasmuch as the cleaning may be effected more expeditiously thereby than by other kinds of devices. The accompanying drawings show two illustrative embodiments of the invention, comprising exterior-'cleaning devices on the order of ,those of the said Letters Patent, and blowen jet devices for clearing out the bobbin bores.

In the drawings,` Fig. l is yan end elevation of a portion of the machine of the LettersPatent aforesaid, l\l o1,1i51,239, of April 10, 1923, having combined therewith a bobbin supporting and guiding apron and one arrangement ofv blower-jet device. u

Fig. 2 is a side view of the parts that are shown in Fig. l.

Fig. 3 is a sectional detail view on an enlarged scaleshowing a bobbin in position for being operated upon by the jet of air from the blower-nozzle. Y l

Figs. 4, 5 and 6 are views similar to Figs. l, 2 `and 3, showing a slightly different arrangement of parts.

Having reference to the drawings,-

At l is indicated a portion of the machine of the Letters Patent aforesaid for removing or `stripping the residue of Waste from the outside of spent bobbins, only so much ofthe said machine being shown as is needed for an understanding ofthe present invention. Preferably the device for clearing ont material such as has been mentioned from the .bobbin bores is applied to the discharging chute or apron 2, which is suitably mounted on the base 3 of the machine, and down which thle1 externally cleaned or stripped bobbins ro In the case of each of the illustrative embodiments of the invention which are shown in the drawings, a current or jet of air directed lengthwise of the bobbins, in other words moving axially with respect to t-he bobbins, is brought'to bear on them, either while they are still in the grip of the machine or as they roll down the chute or apron 2, so as to enter the bore or interior of a bobbin at one end of the latter and expel at the other end of the bobbin any fragments of roving, lint or dirtthat may have lodged within the said boreV or interior. Inasmuch as many bobbins have a bore that is not uniform in diameter from end to end of the bobbin but is smaller at one end than at the other, the air should be directed into the smaller end to assure free exit from the large end of the matter required to be expelled.v In the case of each of the said illustrative embodiments an air-nozzle is mounted by means of an elbowV 6 on the upper end ot an upright pipe 5 which at its lower end is connected With a source of supply ot' compressed air. The arrangement of the air-nozzle is such that the jet issuing from said nozzle is projected transversely across the path of movement of the externally cleaned bobbins. In Figs. l, 2, 3, the air-nozzle t is located in a position Which causes the jet of air to act upon the bobbins as they roll down the apron or chute 2. ln F 4, 5 and 6, the nozzle 7 is arranged to bring the air-jet issuing therefrom in line with the bore of each bobbin the instant the latter emerges from beneath the lower edge 8 ot the housing at the discharge opening, so as to let the air-jet enter the bore before the bobbin .has gained headway in falling away from the mechanism by Which the bobbin-exteriors are cleaned. lf desired, the nozzle may be located in such position in respect to a suitable hole in the housing ot the stripping machine l? that the jet of air Will register with the bores of the bobbins as they are being ied along within the machine While they still remain in the grip oi' its feeding mechanism; in this case provision will be made tor escape of the roving, lint7 etc., discharged from the said bores through an opening at the opposite side of the said housing.

' The use of the presentinvention is not conined to roving bobbins7 but it is equally within the scope ot the invention to apply the principles involved to the cleaning of the bores of illing bobbins.

Nhat is claimed as the invention is i. In a bobbin-stripper, the combination with mechanism for stripping residues or waste from the exterior of bobbins7 and conveying means for the bobbins operated upon. of a jet device located adjacent the path ot the bobbins and arranged to sendl a of air through the bore of each bobbin as the latter passes the jet device. y

2. In a bobbin-stripper, the combination With mechanism for stripping residues or Waste from the exteriors ot bobbins, and means `for conveying the said bobbins With their length disposed transversely With relation to the path of movement, of means for causing concentrated flow of air transversely across said path and through the bores of the bobbins While they are moving by in succession.

3. A bobbin-stripper comprising, in combination, mechanism for stripping residues or Waste from the exteriors of bobbins, and means located at the discharging end ot Such mechanism` operating to clear out the bores of the bobbins by a concentrated jet of air moving axially with respect to the bobbins and directed through the bore of each individuai bobbin in succession as the respective bobbins travclpast said jet in being discharged from the stripping mechanism.

- 4l. A hobbin-cleaning machine comprising, in combination,'means for stripping residues or Waste Jirom the exteriors of bobbins, a chute .to ca y the externallystripped bobbins away ii m the said stripping means, and mea.. for cleaning the interior of the bobbins consi ting an air-nozzle connected With a source oi1 air unt er pressure and directing its jet of air to enter the interiors of the bobbins as they pass along said chute.

A bobbin-cleaning machine comprising combination a chute down Which bobbins designed to roll, an air-nozzle located in i@ proximity 'to the path followed by one end r each bobbin as it thus rolls down7 and means i-'or causing a concentrated jet oi air to flow from said air-noZZle through the bore oi each bohbin as the latter rolls past.

6. A bobbin-cleaning machine comprising7 in combination with mechanism for stripping residues or waste from the eXteriors of bobbins, a chute down which bobbins are deied to roll, an airnozzle located in proximity to the path followed by one end of each hobbin as it thus rolls down, and means for causing a concentrated et ot' air to iiow from said air-nozzle through the bore of each bobbin as the latter rolls past.
